posteriorly; basal angles broadly rounded; apical more narrowly so; disk 

 evenly and moderately convex, rather broadly and gradually explanate and 

 feebly reflexei at the sides, and especially near the basal angles, very obso- 

 letely impressed along the middle and in front of the scutellum, finely reticu- 

 late or snbalutaceous, very finely, feebly and rather sparsely and evenly 

 punctate. Elytra at base very slightly narrower than the prothorax; sides very 

 feebly divergent, feebly arcuate; disk depressed, very slightly longer than wide, 

 two-thirds longer than the pronotum, rather strongly, coarsely and sparsely 

 punctate; intervals polished; puuctures tending to form coarse, transverse 

 rugulae. Abdomen as wide as and distinctly longer than the elytra; sides 

 rather feebly convergent posteriorly, on the first four segments feebly arcu- 

 ate; border depressed, scarcely at all inclined; surface polished, nearly im- 

 punctate in the middle, excessively minutely and feebly puuctulate toward 

 the sides. Legs slender; anterior tarsi very feebly dilated; first joint of the 

 posterior as long as the next three together. Length 2.5-3.6 mm.

Described from the male, which is more slender than the 

 female. The species belongs near puberulum Fauv., but 

 differs in its longer elytra and much sparser elytral punctu- 

 ation. 



A. veteratOf n. sp. — Moderately robust, depressed, dark piceous-brown; 

 antennas toward base, narrow side and basal margins of the pronotum, and 

 under surface of the head and prothorax, pale testaceous; abdomen black 

 throughout; femora piceo-testaceous; tibiae and tarsi darker, piceous; anten- 

 nae infuscate toward tip; palpi fuscous; head and pronotum subalutaceous; 

 pronotum and elytra finely and densely pubescent, the latter shining. Head 

 rather small, scarcely as wide as long, transversely and feebly impressed be- 

 tween the antennas, very finely, feebly and obliquely bistriate between the 

 eyes; surface rather coarsely and strongly reticulate or subgranulate, impunc- 

 tate; ocelli very small, round and distinct; antennae about one-half as long as 

 the body, moderately slender, all the joints distinctly elongate, joints four to 

 ten almost equal in length, the latter nearly one-half longer than wide, second 

 distinctly shorter than the third, the latter subequal in length to the first. 

 Prothorax anteriorly as wide as the head, widest in the middle; sides very 

 slightly more strongly convergent anteriorly than posteriorly, evenly and 

 rather feebly arcuate throughout; apex distinctly narrower than the base, 

 broadly and feebly sinuate; the latter truncate in the middle, broadly arcuate 

 toward the basal angles which are broadly rounded; apical broadly rounded, 

 slightly less so than the basal; disk nearly one-half wider than long, evenly 

 and very moderately convex, rather abruptly and very narrowly explanate at 

 the sides anteriorly, broadly and very gradually explanate and feebly reflexed 

 toward the basal angles, very obsoletely and vaguely impressed before the 

 scutellum, finely and very feebly subgranulate, very minutely, feebly, subas-
